The symbol −10X used to represent which of the particles?

The symbol -10 X is used to represent electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. The negative charge of an electron is denoted by the symbol -1, and the atomic number of an element represents the number of protons in the nucleus. Therefore, the symbol -10 X represents 10 electrons. It is worth noting that this notation is often used in physics and chemistry to represent the charge and number of electrons in a system. In comparison, protons are positively charged particles found in the nucleus of an atom, and neutrons are neutral particles also found in the nucleus. Atoms are the smallest unit of matter that retains the chemical properties of an element.
